This 1987 Centurion Ironman was one of the worst rusted and corroded bike I bought from CL. All the bearings were rusted fast and nothing would move. 90% of the paint came off with my fingernail. I love Centurions so here is what I did to it. It is now almost Identical to Bob Rolls 1987 7/11 team bike. It even has the airfoil spokes.
